Bio Advanced Carpenter Ant & Termite Killer Plus Concentrate is not labeled for applications inside a barn.
Tempo SC Ultra could be used in areas like barns as long as it does not contaminate the hay or other food or animal feed and the hay does not contact the areas treated with Tempo. You could use Evergreen Insecticide to treat an area before hay is stored there. Please see our Spider Treatment Guide for additional tips.
